Seagen 1.2MW - Strangford
MCT Seagen 1.2MW• Licensed by EHS NI in 2005, and reissued with changes in 2008• Marine Construction and Commissioning completed in 2008• Initial 5 year license was extended till 2019 when
decommissioning was completed• Adaptive management strategy for FEPA license allowed
continual improvement from EIA operations
• Comprehensive report on EIA by Royal Haskoning• Keenan, G.; Sparling, C.; Williams, H.; Fortune, F. (2011). SeaGen Environmental Monitoring
Programme: Final Report. Report by Royal Haskoning. pp 81.
• Exported 11.9GWh in 8 years of operation, powering 1,500 homes
• Local Marine Operators (Cuan Marine Services) now commissioned for Meygen marine operations – Local Knowledge
Operational Turbine has had no negative impact on Environment

TTT Projects Outputs.. So farImproved methodologies for assessing turbine power performance data• Direct contribution to new Standards IEC TS62600:202 ‘Scale testing of Tidal Energy
Converters’.• Feedback to IEC Maintenance Team for IEC TS62600:201 for new edition ‘Power
performance assessment’• Significance of the control strategy operated in subsystem testing
The key parameters for power/ loading regimes• Wave loading significantly greater impact than flow misalignment• Turbulence intensity a function of velocity.
Array Spacing• Wake recovery within 6D downstream of turbine• Constructive interaction through device spacing detectable

Flex Marine Power 2020
Flex Marine Power are excited to be working with Queens University Belfast (QUB) to carry out tidal energy research in the Narrows tidal channel, Strangford Lough. Based in Scotland, Flex Marine have been developing their community-oriented tidal energy technology since 2015. Marine operations have now commenced at QUB's test site, being delivered by local outfit Strangford Moorings. Activities in the Narrows are scheduled to be completed before Christmas and the work aims to demonstrate the ability of Flex Marine’s technology (a floating buoy with a horizontal axis turbine mounted underwater) to generate clean, predictable energy from our oceans.
• Worked closely with DEARA for short term experimental campaigns
• EIA a key part of each project
